Definitions

  • the present invention relates to a mixture for cleaning and disinfecting milking equipment.
  • the alkaline agent is used in the morning and the acidic agent in the evening.
  • this solution is poured into the sewage system.
  • This cleaning method which requires the alternate use of two different products, has a number of disadvantages.
  • Chlorine also has oxidizing properties which enable it to react with organic substances, including the milk residues found in milking equipment; Some of the chlorine is therefore neutralized by the milk residues before it can develop its disinfectant properties.
  • Another disadvantage of the conventional agents used for cleaning and disinfecting milking equipment is related to the low thermal stability of chlorinated substances: in summer, the temperature in the trucks with which the agent is transported and in the warehouses can 60 ° C, which entails the need to provide degassing valves in the canisters containing the agent to allow the escape of chlorine, which is then missing at the time of use.
  • regulating elements controlled the filling of water into the tank for a predetermined period of time in accordance with a predetermined amount of water; in this way it was ensured that the required amount of water was always available, even if the mixture was to a large extent k foamed, as is the case with the mixture described in patent FR 86 11 839.
  • the probe shuts off the water supply very early on due to its foaming properties, without the amount of water required for cleaning being available.
  • the milking equipment has many rubber parts which, due to their rapid wear and tear due to the combined action of the cleaning and disinfectant mixture and repeated mechanical stresses, are replaced very frequently.
  • Cleaning and disinfection of milking equipment proposes that has the advantage of combining detergents and disinfectants in a single phase, but at the same time not only being bactericidal and fungicidal, but also virucidal and, above all, not foaming, or only very slightly, what its use for cleaning and disinfection of new tanks equipped with a level probe.
  • This mixture is characterized in that it contains between 20 and 80 percent by weight of one or more strong acids and between 0.5 and 10 percent by weight of at least one anionic, essentially low-foaming surfactant.
  • the strong acids play the role of decalcifying agents and take over part of the washing action; it can be mineral acids or organic acids; 75 * phosphoric acid may be mentioned as an example of a usable acid.
  • the acidic character of the mixture makes it possible to automatically solve the problems associated with water hardness and to avoid the need to use a complexing agent.
  • the anionic surfactants which can be used according to the invention are conventional surfactants such as alkyl benzene sulfonates, lauryl sulfate, alkane sulfonates in general etc. These surfactants, which are well known as cleaning agents, are only very little dissociated in view of the acidic nature of the mixture and therefore actually mainly play a disinfectant role as a bactericide, but also as a virucide.
  • the surfactant preferably consists of a mixture of a large amount of an anionic, not or very little foaming, but moderately disinfectant substance, which is approximately 5 * of the total
  • the mixture also contains a salt of a fatty acid in an amount of approximately 0.1 to 2 percent by weight.
  • This salt which can be derived in particular from a fatty acid with Cn, serves as a bactericidal or fungicidal disinfectant; it also has a certain anionic character.
  • the mixture contains an alcohol, in particular ethyl alcohol, which plays the role of a solubilizer.
  • the mixture according to the invention is moreover intended to be used in a concentration of the order of about 0.5 to 1 percent by weight.
